I suspect that all 4 of these slideshows will be linked from the MLA web site at some point, but I may as well link them up here, too! [Edited: Perhaps I should have mentioned that the other 2 slideshows are the blogs/wikis one by Amanda Etches-Johnson and the RSS/social bookmarking one by Melissa Rethlefsen that I linked in the previous post...]
These are the 2 other Web 2.0 Plenary slideshows, the first from David Rothman and the second from Bart Ragon.
Web 2.0 (David Rothman)
APIs, Mashups, and the Semantic Web (Bart Ragon)
Know of any more? Let me know!
